Mob B is claimed to be a flying monster that has currently no name except for mob B. It is suggested that it will spawns at high altitudes in groups and will fly
towards the player. It is said that it will be attracted to players with insomnia or those who haven’t slept for a while. It currently has no other facts but Jeb_ says that Mob B should be in the game because there really aren’t any flying monsters yet- except for Vex and parrot. It also was the one that won the vote in minecon earth. It will be added with the aquatic update that was also announced on minecon earth.
